Abstract

The invention relates to weeding composition containing diflufenican and flumetsulam, which is mainly characterized by comtaining 1 percent to 80 percent of diflufenican, 1 percent to 60 percent of flumetsulam, auxiliary agent and other excipients. The weeding composition can be made into wettable powder, water dispersion granule, suspending agent, suspension emulsion, water emulsion and micro emulsion. The weeding composition can be used for preventing the weeds in wheat field and has the characteristics of less use of farm chemicals, less residue of farm chemicals, good environmental compatibility and safety to the human beings and animals.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing diflufenican and flumesulam, which is used for preventing and controlling weeds in wheat fields. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the pesticides with complementary properties can obtain the ...
